TYPE-'WRITER PAPER-FEEDING NIECHANISWIl Specification ofLetters Patent.

Patented Oct. 16, 1.906.

Original application filed Jun'e 2, 1902, Serial No. 109,925. Dividedand this application filed March 9, 1903. Serial No. 146,900.

Be it known that l, Jesse ALEXANDER, a citizen of the United' States,residing at Brooklyn, in the county of Kings, State of New York, haveinvented certain new and useful improvements in Type-Writer Paper-Feeding Mechanism, of which the following is a full, clear, and exactdescription.

My invention relates to improvements in type-writers, and particularlyto the mechanism for feeding the paper about the platen in that classhaving a revoluble platen.

This is a divisional application from the application filed by me June2, 1902, serially numbered 109,925.

The object of this inventionis to effect a proper feeding,l of the paperabout the platen or roller and to provide a means for releasing thepressure of the guides uponthe platen by l also provide a meansguiding-rollers.

llt is also my object to provide an introductory guide which may beremovably attached to the general carriage structure and make thestructure compact.

The invention consists in the structure and arrangement' of anintroductory guide, a shield or lower guide, and of the presser-rolt ersand the general location and construction of the parts, as will morefully appear on an examination ofthe following specification l and theaccompanying drawings.

Figure 1 is a plan view of those parts of the type-writer carriage andguides which embody my invention. Fig. 2 is a plan view of 'thepresser-rollers and the releasing and adjusting mechanism therefor. Fig.3 is a eross-section and end elevation of the parts of a carriagestructure embodying my inven tion. Fig. 4 is arear view of theintroductory guide, the central part being broken away. Y

1 is the introductory guide by means of which the paper is 'first led tothe rear of the platen 2.

3 is the lower guide or shield, which is sel cured to the bar 4 andextends downward slotted at the lower ends, as shown particularly inFig. 4. therefore be readily attached to or f lctaehed from the bar 4and the other parts of the car ringe structure to be described by simplyadjusting the screws 5 5.

7 7 are side plates which constitute part of the carriage structure andin which the bar 11 finds its support. 8 is alplaten-shaft, which hasbearings in these plates 7 7 and is pro vided with the handles or knobs.Q 0.

10 is one of the rear presser-rollers which are provided, three innumber. Obviously the roller might be made a continuous one from'end toend, but it is preferred to form it in sections.

11 11 are frontA presser-rollers which are provided to act in a mannersimilar to the rear rollers 10 for the purpose of holding the paper inclose contact'with the platen.

101 is a rod which is carried by the 'side plates 7 7 and carries' thearms100 and 110, by means of which the rollers 10 and 11 receive theirsup ort.

102 is a shaft on which the rollers 10 are mounted. The arms 100 arepreferably slotted to receive the ends of the shaft 102, so that whenthe arms are retracted the shaft 102 may be removed, together with therollers 10 10, if desired.

The rollers 10 and 11 are pressed toward the platen 2 by means of ahelical spring, which is preferably formed in two sections 112 and 113,connected together by means of the ratchet 114. The pressure which.these rollers' l0 and 1l exert against the platen may be readilyadjusted by simply turning the ratchets 11a to either increase ordecrease the torsional effect of the springs 112 113.

150 is a lever which extends upward, so as to be readily reached, Thisis connected to the shaft 15, which is pivoted in the side plate 7 7 ofthe carriage. 105 105 are arms carried by this shaft 15, which mayextend forward and, being slotted the end, thus engage the ends of theshaft 102. Pressure upon the lever 150 will rock the shaft 15, and thusretract or release the rollers 10 from their pressure against theplaten, so that the .paper may be adjusted as desired.

13 13 are spring-finger guides which are provided at the front of theplaten for holding the paper securely at the edges. These Theintroductory guide may IOO . guides are preferably slidably mounted uponprinting position, so that it sha l`lie out of the auxiliary platen andshifting rod 131, which is carried by the side plates 7 7, the lowerends of the fingers being bent up to surround the rod.

`14 is an auxiliary guidein the form of an inverted frame, the ends ofwhich may be slippedinto recesses in the bar 140, which-is a art of thestationary frame of the machine-v 01 instance, the type-bar plate. Thisframe 1li is preferably formed of spring metal, so as to be held inplace by virtue of its own tension. 141 is arollercarried by this frame14 for the purpose of assisting in guiding the paper at or near thecentral portion. This guide being supported b the machine forms ameans-for holding bac the pa ernear the the Way of. the printing-type,which are adapted to operate on a horizontal line visible to theoperator.

What l claim is- 1..n,a type-writin machine, a carriagefraniea platencarrie thereby, a rod carried by said, frame at the rear of said platen,a paper-guide shield secured at the rear to said rodand extendingdownward and upward around the lower side of the platen, a scale carriedby the front edge of said shield,` screws threaded into said rod, and apaperintroducing guide removably secured to s'aid rod by said screws.

2. A type-writer-carriage construction including side frames, a platenmounted 'therein, a rod carried by said frames'at the rear of saidplaten, a shield attached to said rod and extending underneath and infront of saidplaten, an introductory paper-guide comprising a curvedmember extending between the side frames and at the rear of the platen,l

ed to be engaged b the linger, and a slotted arm engaging the s aft uponwhich said rollers are mounted.

4. A typewriter-carriage construction including side frames, a platenmounted there- 5 5 in, a rod carried by the side frames and beneath theplaten, a spring-pressed shaft at the rear of said platen pivoted onsadiOd, pressure-rollers mounted on said shaft, a sec-1 ond shaftpivoted in carriage side frames, a slotted arm secured to saidsecondshaft engaging the roller-carryin shaft and a lever secured to saidsecond s aft adapted to be. engaged by the finger for retracting saidrollers.

5. A type-Writer-carriage construction including'side frames, aplatenmounted therein, a rod mounted beneath said platen,`a pair ofspring-pressed arms pivotallycarried by said rod and slotted in theends, a pressureroller-carrying shaft having its ends resting in saidslots in said arms, a retreating-shaft pivoted in said frames'and havingan arm with a slotted. portionengagino' the roller,-

carrying shaft and an operatingever carried 7 5 by saidretracting-shaft. l
